APPARATUS FOR TWISTlNG TOGETHER ENDS OF THREADS OF WOUND BOBBINS.

SPECIFICATION forming part of Letters Patent No. 668,193, dated February19, 1901.

Application filed January 18, 1900. Serial No. 1,937. (No model.)

During the rotation of the bobbin these two thread ends are twistedabout each other until after a certain time they slip from between thesprings. By treating a number of bobbins in this way the bobbins aresuccessively pushed out of the bobbin guide. As the thread ends aretwisted about each other, entangling is effectually prevented. The rods7 and 8 after having pushed out a bobbin are moved back again, when therocking frame is brought back into its original vertical position readyto receive a fresh bobbin.

Instead of the rotary bobbin-guide a stationary one may be used. In thiscase the flat springs 11 are given a rotary motion to bring about thetwisting of the thread ends. This modification is illustrated in Figs. 5and 6, which will be understood without further description.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In an apparatus for twisting together the ends of threads of woundbobbins, the combination of a journal or guide for the bobbin, asecuring device for holding the ends of the bobbin-threads, and meansfor producing a relative motion between the two, whereby the ends of thethread are twisted together.

2. In an apparatus for twisting togetherthe ends of threads of woundbobbins, the com bination of two machine elements, namely, a journal orguide for the bobbin and a securing device for holding the ends of thebobbinthreads, one of which elements is stationary and the othermovable, whereby the ends of the thread may be twisted together.

3. In an apparatus for-twisting together the ends of threads of woundbobbins, the combination with two machine elements, namely, a journal orguide for the bobbin and a securing device'for holding the ends of thebobbinthreads, of means for producing a relative motion between the saidtwo machine elements, whereby the ends of the threads may be twistedtogether.

4. In an apparatus for twisting together the ends of threads of woundbobbins, the combination of a rotatable journal or guide for the bobbin,and a stationary securing device for the ends of the thread, whereby arelative motion between the two results.

5. In an apparatus for twisting together the ends of threads of woundbobbins, the combination with a journal or guide for the bobbin, of asecuring device for the thread ends, and

means for producing a relative motion between the two and forwithdrawing the twisted ends from the securing device.

6. In an apparatus for twisting together the v 7. In an apparatus fortwisting together the ends of threads of wound bobbins, the combinationwith a journal or guide for the bobbin, a securing device for the endsof the bobbinthread, a feed-hopper, a rocking frame arranged to receivebobbins from the hopper, means for yieldingly holding the rocking framein its normal position, mechanism for tipping said rocking frame andholding it in a tipped position, and means for operating said mechanism.

8. In an apparatus for twisting together the ends of threads of woundbobbins, the combination of a guide or journal for the bobbin, asecuring device for the thread ends of the bobbin, means for producing arelative rotation between the two, a rocking frame underneath a hopper,a spring for holding the said rocking frame ordinarily in a horizontalposition a rod adapted to tilt the said rocking frame and to hold it inthe tilted position, until a new bobbin has to be introduced and meansfor imparting a reciprocating axial motion to the said rod,substantially as set forth.

9. In an apparatus for twisting together the ends of threads of woundbobbins, the combination with a journal or guide for the bobbin, asecuring device for the ends of the bobbinthread, means for producing arelative motion between the journal or-guide and the securing device,and a brush arranged in advance of the securing device to wipe thethread ends so that they may be grasped by the securing device.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.
